Haven't used the Galaxy N7000, but have not been impressed by the camera capabilities of any of the iPhone/Android/etc. devices. To equal even pretty basic dedicated cameras would require a much better lens with decent zoom capability, a larger sensor, and better flash. If you'd be satisfied with only taking pictures in good light, without zoom, and don't plan to view them on a large screen, then it'll probably work fine. But I wouldn't be happy with those restrictions.

OTOH, I hardly care at all how good the screen is on the camera and usually leave it turned off. I do my picture editing on a PC later, so the screen on the camera is pretty irrelevant except to be able to show the pictures to others who are on the trip with me.
